CPU Heats

[atreya2011]

Recently I noticed that while I am encoding @ VHQ 4 with XviD(which significantly reduces the encoding time) my cpu temperature increases by 15 C. Is that normal?

Since I have no air conditioner in the room where my computer is present and I cant afford exotic cooling solutions I am planning to use 2 94 CFM fans on the cabinet to cool the CPU. Is that a good idea

I would suggest buying a better heatsink for the CPU (even if you have one already on the CPU). I have a Vantec Aeroflow on my CPU and I can over clock a 2.6 Ghz P4 up to 3.12 Ghz with no problem. Even encoding at 3.12 Ghz is fine. Here's the link to Vantec:

Its the same brand PCMag put into one of their PC's they built by scratch...There are others but this is a good one and pretty cheap (only like $20-$25 on eBay, where I got mine :D )

I cant afford exotic cooling solutionsGood watercooling isn't necessarily very expensive if you buy on ebay. I just bought an Eheim pump, Innovatek reservoir and IceRex radiator for only 63 Euro altogether. Add a fairly good waterblock, a 120mm fan and some tubes and you're still below 100 Euro (respectively dollars).
If you don't mind the noise then buy a Vantec tornado or a Delta.
I rather switched to watercooling.

What pc do u have firstly (specs)(also what fans and stuff has it got)

secondly whats your idle temp and thirdly whats your fully loaded temp
both cpu and any other temps u can measure ie internal case temp or mb temp?!!

cos if it jumps 15 degrees but is still low then all is good need more information before passing judgement

My Basic Specs are in My Sig.
The heatsink is the stock heatsink that came with the processor
And My Comp isnt oced, everything is running at stock speed

Heres the shocking part

Idle temp is 54 C
Fully loaded temp (either while playing games or encoding) is 70 C

Sometimes its even gone way up to 80 C (rarely) although I have configured the BIOS to shutdown automatically in those rare cases.

If this is measured from an external diode then it's way too hot!!
If the temps are from the internal Athlon temp diode (depends on what your board reads and reports) you can subtract about 13-15° and you're OK up to 70°C - however 80°C is still too hot then. Not that it would harm the CPU yet, but you can't expect to have a stable system in these regions.

In my experience, Athlons (last tested: XP1900+) become more unstable above 50°C (measured from the external diode). I tested with Prime torture test and got errors as soon as it reached more than 50-51°C. This was in summer when my room temp hit 32°C, and that was the reason I switched to watercooling.
However I first bought a Thermaltake set that proved to be ok, but not extraordinary (I figured I might still get more than 50°C load temp when it's above 30°C room temp...) so I'm upgrading :)

btw my sys:
AthlonXP 2700+ (Toroughbred)
Thermaltake Aquarius II watercooling
Epox 8K5A2+ (with HPT Raid)
512MB Corsair XMS PC 2700
ATI Radeon 7500 retail
Philips Acoustic Edge PSC706
2 x IBM GXP120 120GB (7200 rpm)
1 x 60GB Western Digital (5400 rpm)
Pioneer DVR A06 DVD-R/RW, +R/RW, ATAPI
Leadman Powmax 400W PSU
Chieftec CS601 case (black/blue)
4 case fans: out: 2 x Pabst NGML (27 cfm), in: 2 x Noiseblocker S4 (45 cfm)

There's a good reason why the CPU heats up when it's doing work, and that is that it's doing work...

If it's stable, then it really isn't worth worrying about. It is worth cleaning dust out of the heatsink and clearing up the airflow within your case though, since that's pretty simple to do.

If it starts crashing, then you've got an issue worth worrying about on your hands. In which case keep reading... :)

I assume that your Athlon is using a Palomino core, judging by the temperatures. Just to put it in perspective the Palomino based 2000+ puts out as much heat as the current 2800+, so if you do indeed have a Palomino 2100+ you have one of the hottest CPUs around... and that definitely doesn't help.

A 1.8GHz Duron wouldn't be a bad option, as they're cheap, run cool, and perform better than you'd expect...

[jeremymacmull]

get a better heatsink like the zalman 7000a or something also use thermal paste between the heatsink and the cpu (arctic silver stuff is very good) that should reduce temps by a lot

70 is WAY too high 80 is ridiculous

... also check your case cooling: is there at least one fan out at the back and/or one in at the front? Is there a mess of cables everywhere so no airflow is possible?

Aircooling depends very much on the air temperature inside the case --> you need to get fresh air in and hot air out, otherwise no cpu cooler will help you!

[atreya2011]

@b00zed

Yup I have a Palamino, not a tbred. And Durons arent available here. :(

@jeremymacmull

I am planning to buy a Thermaltake heatsink (undecided on the model). Thermaltake is good enough right?

@theReal

And I am planning to attach 2 94 CFM fans to my cabinet ( i dont have any external fans right now) One blowing in and the other blowing out. Is that a good Idea?

For how long you are doing this now ???

Maybe I should buy one of thus AeroFlow's too... :rolleyes:

Btw, its maybe offtopic but I found out that my Radeon9800Pro is a downclocked Radeon 9800XT... :D

Need only some new cooling to run it as a much more expensive 9800XT !!!

But 94cfm is a little much, don't you think? What kind of fans are these? 120mm?
As you can see in my system description above, my strongest fans are 80mm, 47cfm - but they are regulated by a potentiometer and I hope I never have to run them at full speed again (they are pretty loud at full speed!)
The Pabst NGML at the back run at full speed because they run very silently at 19dB anyways (but only have 27cfm each)

[atreya2011]

Here are the exact specs of the fan:

Size: You guessed it right - 120mm :D
Current: 105mA
Power: 19 watts
Speed: 2550 rpm
Airflow: 95 CFM (not 94 hehe)
Noise: 42 dbA (Stupid Question: Is that Loud?)

And 9500 non pro can be modded to 9700 pro i think, anyways thats what my friend did, he enabled 4 pipelines disabled in the 9500 non pro he had and oced it to 9700 pro clock speed. And boy do I feel stupid :D.

[jeremymacmull]

thermaltake are good there are others which are better but thatll do the job fine

get some thermal paste aswell ie the arctic silver type stuff itll do wonders for temps remember to fit the cpu cooler on correctly otherwise it does no good at all

94cfm whoah ive got 80mm's and they do like 30 cfm a bit overkill i think

I don't think that always holds true. I've run my Athlon XP 2400+ (and before that a 1700+ one) for hours at up to 70C and I must say it has always been solid rock stable.

Is there any way to find out if the reported temperature is taken from a external or internal diode?

I've been doing this since December when I built my PC. I have an Asus P4P800 Deluxe motherboard and it has really helped the overclocking. I'm encoding a movie with CCE right now and it's at a cool 45-46 C
:D . I saw over on overclockers.com and from a couple of the user reviews on newegg.com that people have been able to overclock it to 3.4 Ghz without any problems. The Asus motherboard also has a variable fan speed setting where if the CPU or motherboard start to get hotter, the fans speed up to cool them off. And when things are cool, the fans slow down. Sorry to be off-topic but I just thought I'd respond.

One last question:

Is removing the old van n' adding a new van compliacate... :confused:

Have never done this before, so could you maybe provide some hints ???


Tia n' Bye

The CPU heatsinks have to match the type of processor you have in your computer. Since you have an AMD Athlon 2600XP, you would probably need one of the type "Socket 370, 7, A" on the Vantec website:
http://www.vantecusa.com/product-cooling.html#

It may be best to call the customer service of Vantec just ot make sure it will fit your CPU.
